BARREL-HOOP-DRIVING MACHINE Specification of Letters Patent.

Application filed September 22, 1909.

To all whom it may concern.'

Be it known that we, WILLIAM C. STEVENS, of Akron, in the county ofSummit and State of Ohio, and ALEXANDER MAcGnEGoR, of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, both citizens of theUnited States of America, have invented a certain new and usefulImprovement in BarreLHoop-Driving Machines, of which the following is atrue and exact description, reference being had to the accompanyingdrawings, which form a part thereof.

Our present invention relates to machines for driving or setting hoopson barrels, casks and the like.

The object of the invention is the provision of a driving headconstruction which is simple, reliable and powerful in operation, is notapt to get out of order, can be easily adjusted to barrels of differentsizes, and has provisions for readily and positively moving the drivingarms radially outward when necessary before and after driving one of theintermediate hoops onV the barrel so that the driving arms will clearthe end hoop or hoops of the barrel, while at the same time each drivingarm has freedom to aocommodate itself to any irregularity in the contourof the barrel during the hoop driv- Ving operation, but is held againstjumping over the hoop being driven.

A further ob'ect of the invention is the provision in a riving headhaving driving `arms for setting the intermediate hoops of -a barrel, ofa suitable resiliently supported presser plate for engaging the end hoopof the barrel and driving it in place either at the same time that theintermediate hoop is being set, or at a different time.

The various features of vnovelty which characterize our invention arepointed out with articularity in the claims annexed to and orming a partof this specification. For a better understanding ofthe invention,however, reference should be had to the accompanying drawings anddescriptive matter lnwhich we have illustrated and described in detailone of the formsin which Athe invention may be embodied.

Of the drawings, Figure l is a perspective view showing an entire hoopsetting machine exce t a portion of the driving mechanism of t emachine. Fig. 2 is a perspective view, on a Larger scale than Fig. 1,

the like, (not shown), o i which a hoop or hoops is to be driven, is paced. 0n the base A are supported a pair of pedestals or columns A whichare unit ad at the top by a cross piece A2. The driving head, indicatedas a Whole by the symbol D, is provided with guides D sliding on ver'ical guide ways or ribs D6 carried by the columns A. The driving head israised o1 lowered by means of a screw shaft B3 secui ed at its lower endto the driving head, and l Jngitudinally movable through, but heldzgainst rotation in, the cross piece A2. An internally threaded gear B2is journaled in` but held against axial movement in, the :ross piece A2and serves when rotated to raise and lower the threaded shaft B3. Thegear B2 is provided with beveled gear teeth meshing with beveled gear Bcarried by t ie driving shaft B. It will be understood that suitableprovi' sions are made for rotatf ng the shaft B in one direction or theothe r accordingly as it is desired to raise or low 1r the driving headD. We have not thought it necessary to illustrate in detail the coistruction whereby the shaft B is given the desired rotation in onedirection or the other, as clutch mechanism for this purpose is wellknown in this art. It will be sulii cient, therefore, to call attentionto the fact that clutch mechanism may be operated lo stop the shaft B orrotate it in one dire ation or theother through the hand lever X rod X,bell crank X2 and rod X, and that L rod X4, connected to the bell crankX2 and provided with co1- lars Xls and X, and an arm Dx carried by the'head D and adapted to en age the collars X5 and X6, are prow ided orautomati-` cally shifting the clutch :nechanism to limit the extreme upand dowr movements of the head D. Weights Y, ve ftically movable in thecolumns A are provi( Led for counter balancing the weight of th head Dto which they are connected by corl ls or cables Y running over thepulleys Y2 The driving head D cc mprises a disk like body portion D2having a central hub or axially extending portior D. In` the upper endof the latter portici the lower end of the screw shaft 1121s is secured.The body portion D2 is formed with a plurality of radial channels orguide Ways D" at its outer portion, and at the inner end of each guideway D3 is provided with a pocket D5 open at the upper side to receive aspring E2, and the projecting end of a rod E', b means of which a pivotor thrust block i, slidingly received in the corresponding guide way Dais normally held at the inner end of the guide way as shown in Fig. 3.Each block E is slotted to receive a corresponding driving arm F, whichis pivoted to the block 4by a pivot pin E2. The walls of each guide wayD3 are slotted at top and bottom to permit the passage of thecorresponding arm F. Each driving arm carries at its lower end a drivingshoe F', preferably swiveled on the arm. The upper end of each arm F ispivotally connected by a fulcrum pin G to the outer end of acorresponding link G. The inner ends of the links G are pivotallyconnected by pins G2 to ears formed on a collar or ring like member Hwhich is slidingly mounted on the hub portion D2. To accommodate barrelsof different sizes the links may be so formed as to permit of anadjustment of their effective lengths. As shown, this is accomplished byforming two sets'of holes in the outer ends of the links in which thepins G may be placed as desired. The member H is provided with handtrunnion pins H', to which are pivotally connected the bifurcations I oflever I. The latter is fulcrumed on the disk D2 by means of a link Jpivotally connected at its upper end to the lever I, and pivotallyconnected at its lower end to a block or bracket J secured to the upperside of the disk D2. By turning the hand lever I on its fulcrum, themember H may be moved from the position shown in full lines in Fi 3, tothe position shown in dotted lines 1n that figure, and in full lines inFig. l. When the member H is moved into the dotted line position of Fig.3, the pivot ins G2 are lowered, and the fulcrum pins G for the drivingarms F are moved outward, thus throwing the driving-shoes radiallyinward. Attention is directed to the fact that the movement of the leverI is preferably such that the pivot pins G2 are thrown slightly belowthe pivot pins G when the member H is moved into the dotted lineposition of Fig. 3, so that the thrust on the pivot pins G', when thedriving shoes F are moved ra. diall outward, does not tend to move themem er H upward. When driving a quarter or bilge hoop, that is anintermediate hoop, on a barrel or cask, the driving arms are thrown out,as shown in Figs. 2 and 3, until the driving shoes F are moved below theupper end of the barrel and the end hoop thereof, if the latter is inplace, as is usual, although it may not yet have been driven home. Afterthe driving shoes pass-below the top of the barrel, the hand lever I isoperated to move the member H down and force the fulcrums G for thedriving arms F radially outward. This brings the driving shoes intocontact with the barrel, and the parts should be so proportioned thatthe driving shoes will engage the periphery of the barrel before thefulcrum pins G are given their full outward movement so that when thisoutward movement of the fulcrum pins is completed the thrust blocks Ewill be moved radially outward from the inner ends of the guide Ways D2,thus putting the springs E2 under tension. The result of this is, ofcourse, that the driving shoes bear resiliently against the periphery ofthe barrel and tend to draw it into the desired circular form. On thecontinued downward movement of the driving head, the driving shoesengage the quarter or bilge hoop, and force the latter into place. Theresilient manner in which each driving shoe engages the barrel hooprevents any liability of individual driving s oes jumping over the hoopbeing driven. The construction thus permits practically any style ofhoop being driven, and We may remark that the machine shown can be usedwithout change in driving many different styles of hoops, but isparticularly designed for driving the well known spiral wire hoops.-When the hoop engaged by the driving shoes has been driven far enoughthe handle I is operated to slide the member H upward on the hub D4,thus drawing the fulcrum pins G inward and permitting the driving shoesto separate from the hoop be ing driven, and the periphery of the barrelsufficiently to clear the end hoop of the barrel when the head isthereafter raised'. It will be observed that while the tension. of thesprings E may be such that the driving shoes are urged radially inwardagainst the barrel with any desired degree of force, when the member His down, the latter can be shifted through the lever .I by acomparatively small force. The reason for this is two-fold. Themechanism by which the member H and fulcrum pin G is adjusted does nottake the driving thrust of the driving arms. On the contrary, that istaken directly b the disk like body D2 through the thrust blocks E.Moreover the fulcrum links G are so arranged that the leverage is a verypowerful one when the fulcrum pins G are in or near their outerpositions.

In order to drive home the end hoop of the barrel either on the samedownward stroke of the driving head in which the quarter or bilge hoopis driven into fplace, or on an independent stroke, we pre erablyprovide the resiliently supported presser plate L as shown. This presserplate is provided with a centrally located spherical seat on its underside for a washer K having its upper side spherical. The washer Ksurrounds a bolt K provided at its lower end with adjustable lockingnuts K2. The bolt K passes up throu h the pressure plate L into thelower end o? the hub portion D* where a cavity is provided receiving theenlarged head K3 of the bolt K. The bolt K thus serves to limit themovement of the pressure plate L away from the main driving head member,while at the same time the plate has capacity for adjusting its planerelative to the lane of the disk body D2. Between the disk body D2 andthe presser .plate L are Aarranged a plurality of presser springs L2which have f their upper and lower ends receivedv in correspondingAbosses formed on the underside of the disk D2 and the upper side of thepresser plate L.

While in accordance with the provisions of the statutes we have hereindescribed and illustrated the best forms of our invention now known tous, it will be apparent to those skilled in the art that many changes.may be made in the form of the apparatus disclosed without departingfrom the spirit of our invention and that certain features may sometimesbe advantageously employed without a corresponding use of otherfeatures.
